Question

A recipe for rice pudding calls for 2 1/2 cups of milk. The recipe makes 5 servings. How many cups of milk are needed to make 8 servings?

Answer 1

4 cups of milk.

If you do 5/2.5, that will give you the amount of servings per one cup of milk. 5/2.5 is 2, so there are 2 servings per 1 cup. Knowing this, 8 servings would be 4 cups.
